I have installed matlab2019a,mathematica12.1 and frost in ubuntu18.04,and my gcc version is 7.5,then I got the following error:
Invalid MEX-file '/home/sky/frost-dev/third/mathlink/math.mexa64': libWSTP64i4.so: cannot open shared object file
I added the path of the metioned library to the LD_LIBRARY_PATH,but it didn't work.

Sounds like a basic missing files/installation issue. Since FROST is a third-party product, I recommend reaching out to the authors of this toolbox.
